African Skimmer (Rynchops flavirostris)
…a species of skimmer (Rynchopidae) that is native to Africa, where it occurs from Senegal to northern Congo River and southern Nile Valley, southern Tanzania to the Zambezi Valley, and then to KwaZulu-Natal Province and Angola. African skimmers are typically encountered near large tropical rivers with sandbanks, lake shores, and coastal lagoons. Like other skimmers, African skimmers fly over water to feed, using their longer lower mandible to scoop small fish and freshwater invertebrates into thier mouth.
